Romney: 'Middle-income' is $200K to $250K and less

But how does he define "middle-income"? The Republican presidential nominee defined it Friday as income of $200,000 to $250,000 a year and less.

The definition of "middle income" or the "middle class" is politically charged as Romney and President Barack Obama fight to win over working-class voters. Romney would be among the wealthiest presidents, if elected, and Democrats have repeatedly painted him as out of touch with average people.

Obama also has set his definition for "middle class" as families with income of up to $250,000 a year.
